ASPHALT SHINGLE LIMITED WARRANTY
The information below details how IKO supports you after the purchase of your roofing shingles. IKO extends this limited warranty
coverage together with IKO's unique "IRON CLAD" PROTECTION coverage.
In this Limited Warranty certain capitalized words have specific meanings:

terminated, for the number of months set forth in the Information Table.
"Owner" means the owner of the building at the time the Shingles are installed on that building. If you purchase a new residence and
are the first person to occupy the residence, IKO will consider you to be the Owner even though the Shingles were already installed.
"Shingles" means the IKO shingles identified in this Limited Warranty which were installed on a building owned by the Owner.
"Purchase" means the retail purchase of the Shingles.
"Iron Clad Protection Period" means the initial period of the Term during which IKO's obligation is not prorated. The length of the

Only AR designated shingles and Armourshake, Cambridge LT and Crowne Slate shingles are covered by a Limited Algae Resistance
Warranty.
"Square" means 100 square feet of roof coverage.
"High Wind Application" means application of shingles in accordance with the application instructions appearing on the shingle
wrapper with IKO Hip and Ridge shingles installed on all hips and ridges. Some local building codes may require additional fasten-
ers and some shingles qualify for High Wind Application only if the shingles are installed with six (6) fasteners in the locations specified
for mansard applications. See local building codes and application instructions for proper nailing application.

IKO Iron Clad Protection Period: If, during the Iron Clad Protection Period, Shingles that have been installed in strict accordance with the instructions printed on the
wrapper are determined to have manufacturing defects which have directly caused leaks, IKO will have the shingles repaired or replaced free of charge (exclusive of
costs for tear-off of shingles, disposal, flashing and metal work). This is IKO's Maximum Liability during the Iron Clad Protection Period.
After the Iron Clad Protection Period: If, after the end of the Iron Clad Protection Period, Shingles that have been installed in strict accordance with the instructions
printed on the wrapper are determined to have manufacturing defects which have directly caused leaks, IKO's obligation is limited to a prorated amount of the current
value of the shingles only (exclusive of costs for labor, disposal, tear-off, flashing and metal work) or at IKO's option the prorated amount of the dollar limit per square
as provided in the Information Table herein. This prorated amount is calculated by reducing the reasonable replacement shingle cost or at IKO's option the dollar limit
per square as provided in the Information Table herein by the monthly reduction figures for the specific shingles for each month elapsed since Purchase calculated at the
time IKO was notified of a claim related to the Shingles. See Example below. This is IKO's Maximum Liability after the Iron Clad Protection Period.
Example:
A manufacturing defect resulting in leaks is found in 25 year limited warranty shingles in October 2026. The shingles were purchased in October 2008; 18 years, or a
total of 216 months have elapsed since purchase. IKO's liability will be reduced by (180/225 = .80) + (36/600 = .06) = .86. So IKO's maximum liability would be 14%
(100 - 86) of the replacement cost of the shingles.
Both during and after the Iron Clad Protection Period, IKO is not responsible for the cost of any materials other than the replacement shingles (and after the Iron Clad Protection
Period only a prorated amount of the replacement shingles as provided herein). Replacement shingles will be warranted only for the remainder of the original Term.
Notification to IKO: Claims pursuant to this Limited Warranty must be filed (sent pre-paid) within thirty (30) days of discovery of the alleged problem with the Shingles
in the following manner:
a. Contact IKO Quality Services toll-free at 1-800 433-2811 or at productconcerns.us@iko.com.
b. Provide the information as requested by the Quality Services Representative.
c. Complete and sign the Homeowner Inquiry Survey including all of the following:
1. Proof of Purchase which must identify the following: that the shingles are IKO shingles, the type of IKO shingle, the quantity of IKO shingles,
and the date the IKO shingles were purchased.
2. The requested pictures.
3. Two full sample shingles. (If claim is for color concerns, please send two full sample shingles of the lighter color and two full samples of the darker color.)
4. The completed and signed forms.
d. Provide access to the IKO products in question for the purpose of investigation if requested.
Mail claims to: IKO Manufacturing Inc., Attn: Quality Services Department, 235 West South Tec Drive, Kankakee, Illinois 60901-8426
IKO will, within approximately sixty (60) days of receipt of the completed Homeowner Inquiry Survey, evaluate the claim and respond according to any obligations as
may be imposed by the Limited Warranty as a result of such an evaluation. Any claimed defect for which notice is not received by IKO within the applicable warranty
period is not covered by this warranty. Failure to provide requested information may cause the claim not to be considered. Failure of the Owner to notify IKO as pro-
vided herein shall extinguish all liability of IKO under this Limited Warranty and all applicable implied warranties and conditions.
5 Year Limited Wind Resistance Warranty: The Shingles are also covered during the first five years after Purchase by a limited warranty against damage from wind
up to the designated wind velocity per product identified in the Information Table. If additional nails are used for the following shingles, this Limited Wind Resistance
Warranty increases to one hundred ten (110) mph; eight (8) nails for Crowne Slate, six (6) nails for Armourshake and Cambridge LT and four (4) nails for UltraLock
25. This Limited Wind Resistance Warranty applies only if: (a) the Shingles were installed according to the instructions on the wrapper and (b) the Shingles have had
the opportunity to seal down. Shingles that are installed in cool seasons may not seal until weather conditions are adequate to allow the seal down strip to activate. If
conditions (a) and (b) have been met during the first five (5) years after the Shingles Purchase, the Shingles are damaged or blown off by wind up to the designated wind
velocity for the product as a result of a manufacturing defect, IKO will furnish similar replacement shingles for the damaged or blown off Shingles, or alternatively, IKO
will pay for the reasonable cost of manually sealing unsealed Shingles. This Limited Wind Resistance Warranty does not cover the labor costs for the removal of dam-
aged Shingles or the application of the replacement shingles. Any costs in excess of IKO's liability shall be the Owner's liability. Owners may pursue such claims
through their homeowner's insurance.
Shingles will be conclusively deemed to have been exposed to winds in excess of the designated wind velocity for the product if the National Weather Service or other
reputable weather agency records winds in excess of the designated wind velocity for the product in the county, parish, regional district or municipality where the
Shingles are installed or in any adjoining county, parish, regional district or municipality. Exposure of the Shingles at any time to winds in excess of the designated
wind velocity for the product shall extinguish all liability of IKO under this Limited Warranty and all applicable implied warranties and conditions.
5 or 10 year Limited Algae Resistance Warranty for specified Shingles: In the event that within the initial ten (10) year period after Purchase of Armourshake,
Cambridge LT, Crowne Slate, and Cambridge 30 AR and within the initial five (5) year period after Purchase of Gentry Ultra AR, Gentry 25 AR and Marathon Ultra
AR, blue-green algae develops causing discoloration on these Shingles, IKO will issue to the Owner a Labor Payment certificate which may be used to pay the reason-
able cost of cleaning the Shingles up to a maximum of $15 per square. This Labor Payment will be prorated according to the age of the Shingles and be based upon the
number of months elapsed in the limited algae resistance warranty period divided by the 120 months (10 year) warranty period for Armourshake, Cambridge LT, Crowne
Slate and Cambridge 30 AR or 60 months (5 year) warranty period for Gentry Ultra AR, Gentry 25 AR and Marathon Ultra AR. IKO shall have no liability or respon-
sibility for cleaning shingles with algae growth: (a) after the initial period for the product identified in this paragraph, or (b) at any time for any IKO product not iden-
tified in this paragraph. IKO Algae Resistant shingles (that is, the shingle types identified in this paragraph) must be used for hip and ridge areas for this Limited Algae
Resistance Warranty coverage.
Transferability - Armourshake,Cambridge LT & Crowne Slate Shingles only: This Limited Warranty for Armourshake, Cambridge LT and Crowne Slate Shingles
may only be transferred by the Owner to the subsequent property owner within the ten (10) year period following Purchase. Should such a transfer occur, the remain-
der of the Iron Clad Protection Period shall remain in effect (if transfer occurs within the first seven (7) years), and the duration of this Limited Warranty measured from
the date of original shingle installation, shall be fifteen (15) years. The Limited Warranty coverage for years eight (8) through (15) will be as calculated above in "Chart A".
The lifetime limited warranty coverage offered by this Limited Warranty ends automatically upon the sale or transfer of the property or upon death of the last of the orig-
inal owners of the property at the time these shingles were installed.
Transferability - All other shingles: This Limited Warranty for all other IKO shingle products may only be transferred by the Owner to the subsequent property owner
within the ten (10) year period following Purchase. When this Limited Warranty is transferred, the Iron Clad Protection Period shall automatically terminate, and the
duration of this Limited Warranty, measured from the date of the real estate transfer, shall be two (2) years of prorated material only.
This Limited Warranty may only be transferable, subject to the above terms, under the following conditions:
1) Notification of a request for transfer must be received in writing by IKO at 235 West South Tec Drive, Kankakee, Illinois 60901-8426, Attn: Quality Services
Department, from the Owner within thirty (30) days after the date of the real estate transfer. Such requests must include a copy of the original invoice showing proof
of purchase of the IKO product and a copy of the real estate transfer.
2) A transfer fee of $100.00 must accompany all requests for warranty transfer.
Except as provided in the paragraphs titled "Transferability", any assignment, sale or transfer of this Limited Warranty or the building to which the IKO Shingles are
applied shall immediately terminate all liability of IKO for the Shingles, all warranties contained herein or hereunder and any applicable implied warranties and condi-
tions including warranties or conditions of merchantability and fitness for a particular purpose.

Exclusions from Coverage: IKO shall not be liable under any circumstances for:
1. Faulty or improper application of the Shingles, inadequate ventilation of the Shingles or Shingles not installed or applied in accordance with IKO written
installation instructions on the packaging, or leaks or damages resulting from any or more of such causes.
2. Any variation in color or shading or discoloration from any cause whatsoever, including, but not limited to, mold, mildew, fungus, algae, pollutant, moss or
staining from overhanging trees, except as provided in the Limited Algae Resistance Warranty set forth above.
3. Any damage to the interior or exterior of any building or any property contained therein.
4. Tear-off, removal, or disposal of any Shingles, or for any costs related to such tear-off, removal, or disposal.
5. Any damage caused by Acts of God including, but without limitation, lightning, gale or gusts (except as set forth in the Limited Wind Resistance Warranty),
hailstones, hurricane, tornado, earthquake, explosion, flood, or other violent storm or casualty, fungus contamination, solid objects falling on the roof or any
other causes except ordinary wear and tear by the elements.
6. Any damage caused by settlement, distortion or cracking of the roof deck, walls or foundation of a building, including buckling, or for any defect in or
failure of material used as a roof base over which the Shingles are applied, or for damage by traffic on the roof.
7. Any damage if the roof is altered after initial installation of the Shingles, whether any such alteration is by structural additions, changes or replacement or
equipment installations (including without limitation, aerials, signs, water towers, fan housings, air conditioning equipment, solar heaters, water heaters,
television antennas and skylights).
8. Any costs incurred for repair or replacement not authorized in writing by IKO.
9. Any damage caused by algae, fungus, or other biological growth.
10. Any costs related to the removal or abatement of any asbestos present in the roof to which the Shingles are applied.
11. Any damage due to the effects of resins/drippings from nearby trees contacting the Shingles. Such damage may include blisters on the shingle surface.
12. Chemical attack on the Shingles as a result of exposure to chemicals including, but not limited to, aliphatic or aromatic solvents, chlorinated hydrocarbons,
turpentine, oils, organic or inorganic polar materials.
13. Flashings, metal work or required repairs associated with defects or damage.
14. Any backsurfacing transfer or asphalt staining.
15. Shingles installed over insulated roof deck panels or over ventilation which does not meet building code requirements, or for damages caused by insufficient
attic ventilation or roof drainage, or for products installed over a roof deck that is not properly ventilated with an air space between the roof deck and the
insulation. Approximately half of the ventilation must be at the soffit/eaves, with the remaining half at the top, or ridge of the roof.
16. Product bearing "ECONOMY NO WARRANTY" tape as such product is sold as is.
17. Open metal valleys are recommended for best roof performance. Shingles in closed valleys are not covered by this Limited Warranty unless other Shingles
on the roof have manufacturing defects which have directly caused leaks.
18. Discontinuance or modification of any IKO product. IKO reserves the right to discontinue or modify any of its products, including the color blend of its
shingles, without notice to the Owner and shall not be liable to the Owner as a result of this modification or discontinuance. IKO shall have no liability in
the event that replacement material may vary in color in comparison to the original product as a result of product changes or normal weathering.
19. Leaks or damage to the Shingles from any cause other than inherent manufacturing defect in the Shingle.
The limited warranty terms listed in this document apply to shingles installed on roof slopes of 4 in 12 (1:3) and steeper. The limited warranty period for shingles
installed on roof slopes of less than 4 in 12 (1:3) and down to 2 in 12 (1:6) is 12 years (if certain application procedures are followed, see shingle wrapper for details),
and will be pro-rated for material only, exclusive of labor, etc., at an annual reduction of 8.33%. (If certain application procedures are followed, a full limited warranty
will be in effect for slopes between 3:12 to 4:12. See shingle product wrapper for details). Armourshake, Cambridge LT, Crowne Slate and UltraLock 25 will only be
warranted when applied to roof slopes 4 in 12 (1:3) or steeper. Use of an approved underlayment is strongly recommended beneath all Armourshake, Crowne Slate,
Cambridge LT, RoofShake 40, Cathedral SBS, Cambridge 30, Cambridge 30 AR, Gentry Ultra AR, Marathon Ultra AR, Gentry 25, Gentry 25 AR, Marathon 25, Skyline
25 GL and Marathon 20 applications below 6:12.
Any fiberglass asphalt shingles manufactured to meet ASTM D3462 applied to roof deck assemblies (slopes > 2:12) where foam insulation is prefabricated into the roof
deck system (often called “nailboard insulation”), or where insulation is installed immediately beneath an acceptable roof deck system, or where radiant barriers are
installed, with or without ventilation, directly below the deck, shall qualify for a reduced limited warranty duration of 10 (ten) years with no Iron Clad Protection
coverage, with respect to shingle problems related to the absence of adequate roof system ventilation (linear pro-ration over 10 (ten) years). The roof design profes-
sional is responsible to ensure; 1) the proper quality and correct application of the insulation and/or radiant barrier, 2) the provision of adequate structural ventilation
and/or vapor retarders as they determine to be necessary, and 3) that all local codes are met (especially considering local climate conditions). These important factors
and decisions are not the responsibility of IKO but are critical to assure proper deck system performance.
MANDATORY BINDING ARBITRATION: EVERY CLAIM, CONTROVERSY OR DISPUTE OF ANY KIND WHATSOEVER INCLUDING WHETHER ANY
PARTICULAR MATTER IS SUBJECT TO ARBITRATION (EACH AN "ACTION") BETWEEN YOU AND IKO (INCLUDING ANY OF IKO'S EMPLOYEES AND
AGENTS) RELATING TO OR ARISING OUT OF THE SHINGLES OR THIS LIMITED WARRANTY SHALL BE RESOLVED BY FINAL AND BINDING ARBI-
TRATION, REGARDLESS OF WHETHER THE ACTION SOUNDS IN WARRANTY, CONTRACT, STATUTE OR ANY OTHER LEGAL OR EQUITABLE THE-
ORY. TO ARBITRATE AN ACTION AGAINST IKO, YOU MUST INITIATE THE ARBITRATION IN ACCORDANCE WITH THE APPLICABLE RULES OF

Legal Remedies: EXCEPT WHERE PROHIBITED BY LAW, THE OBLIGATION CONTAINED IN THIS LIMITED WARRANTY IS EXPRESSLY IN LIEU OF
ANY OTHER OBLIGATIONS, GUARANTEES, WARRANTIES, AND CONDITIONS EXPRESSED OR IMPLIED, INCLUDING ANY IMPLIED WARRANTY OR
CONDITION OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, AND OF ANY OTHER OBLIGATIONS OR LIABILITY ON THE PART
OF IKO MANUFACTURING INC. IN NO EVENT SHALL IKO BE LIABLE FOR CONSEQUENTIAL OR INCIDENTAL DAMAGES OF ANY KIND. SOME
STATES DO NOT ALLOW EXCLUSION OR LIMITATION OF IMPLIED WARRANTIES OR INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THE
ABOVE LIMITATIONS OR EXCLUSIONS MAY NOT APPLY TO YOU. NO ACTION FOR BREACH OF THIS LIMITED WARRANTY OR ANY OTHER
ACTION AGAINST IKO RELATING TO OR ARISING OUT OF THE SHINGLES, THEIR PURCHASE OR THIS TRANSACTION SHALL BE BROUGHT LATER
THAN ONE YEAR AFTER ANY CAUSE OF ACTION HAS ACCRUED. IN JURISDICTIONS WHERE STATUTORY CLAIMS OR IMPLIED WARRANTIES
AND CONDITIONS CANNOT BE EXCLUDED, ALL SUCH STATUTORY CLAIMS, IMPLIED WARRANTIES AND CONDITIONS AND ALL RIGHTS TO
BRING ACTIONS FOR BREACH THEREOF EXPIRE ONE YEAR (OR SUCH LONGER PERIOD OF TIME IF MANDATED BY APPLICABLE LAWS) AFTER
THE DATE OF PURCHASE. SOME STATES DO NOT ALLOW LIMITATIONS ON HOW LONG AN IMPLIED WARRANTY OR CONDITION LASTS, SO THE
ABOVE LIMITATION MAY NOT APPLY TO YOU. THIS LIMITED WARRANTY GIVES YOU SPECIFIC LEGAL RIGHTS AND YOU MAY ALSO HAVE
OTHER RIGHTS WHICH VARY FROM STATE TO STATE. INVALIDITY OR UNENFORCEABILITY OF ANY PROVISION HEREIN SHALL NOT AFFECT
THE VALIDITY OR ENFORCEABILITY OF ANY OTHER PROVISION WHICH SHALL REMAIN IN FULL FORCE AND EFFECT.

WARRANTIES.
